Math Worksheets for 1st Graders
Free printable 1st grade math worksheets, each with an answer key. No login required.
57 single-skill topics in 10 categories. Each topic has up to 15 different worksheets that print on one page, and every answer is checked by a separate program before a sheet is published.
First grade is where math moves from counting objects to working with numbers on paper. Children learn to count and compare numbers to 100, understand that a two-digit number is made of tens and ones, and add and subtract within 20 with confidence.
These worksheets break that year into single skills. A child who is shaky on number bonds can practice only number bonds; a child who finds clock faces confusing can stay on whole hours until they are secure. Every worksheet prints on one page and comes with an answer key.

What 1st grade students should be able to do
- Count forward and backward to 100, and count by 10s.
- Read and write number words, and name a number as tens and ones.
- Compare two numbers with <, > and =.
- Add and subtract within 20, using doubles, near doubles and number bonds as shortcuts.
- Add and subtract whole tens.
- Tell time to the hour and half hour, and name days, months and parts of the day.
- Name common 2D and 3D shapes, sort objects, and read simple tally charts.
A suggested order for 1st grade math
- Number Charts & Counting — Counting and number words come first; every other skill depends on them.
- Comparing Numbers — Once counting is steady, comparing numbers builds a sense of size.
- Place Value — Tens and ones explain why 34 is not 43, and prepare for adding two-digit numbers.
- Base 10 Blocks — Block pictures make tens and ones concrete before moving to digits only.
- Addition — Start with single-digit facts, then doubles and number bonds to build quick recall.
- Subtraction — Subtraction is easier once addition facts are secure, because fact families link the two.
- Telling Time — Hours and half hours, practiced a little at a time through the year.
- Measurement — Comparing and ordering lengths with everyday objects.
- Geometry — Shape names and positions, a good break from number work.
- Data & Graphing — Sorting and tally marks tie counting to real information.
Tips for using these worksheets
- Keep sessions short. Ten to fifteen minutes on one skill works better than a long mixed page at this age.
- Let a child use fingers, counters or drawings at first. Move to answering without them once the answers come quickly.
- Say the answer key aloud together instead of just marking right or wrong. Ask how they got a wrong answer before showing the correct one.
- If a skill takes three sheets in a row without improving, step back to the topic before it rather than pushing on.

What math should a first grader know?
By the end of first grade most children can count to 100, tell tens from ones in a two-digit number, add and subtract within 20, and tell time to the hour and half hour. Expectations vary a little by school and country, so use the topic list on this page as a checklist and focus on the gaps.
Are the 1st grade worksheets really free?
Yes. Every worksheet is a free PDF with an answer key. There is no login and no email required.
